Description

Technical Field

[0001] This utility model relates to the field of solar backpack technology, and in particular to a wearable solar backpack. Background Technology

[0002] Wearable solar backpacks are innovative products that combine photovoltaic power generation technology with everyday backpack functions. They can meet storage needs and use solar energy to charge electronic devices, making them suitable for outdoor sports, travel, or daily commuting.

[0003] Wearable solar backpacks integrate flexible solar panels on their surface, converting sunlight into electricity to charge devices such as mobile phones, tablets, or computers via a built-in USB interface. However, the size of the solar panels on the surface of existing wearable solar backpacks cannot be changed. If multiple devices are charged simultaneously using the wearable solar backpack, causing the built-in battery to be depleted and the solar panel to be unable to supply the required power to the built-in battery in time, the wearable solar backpack cannot charge multiple devices at the same time. It is necessary to wait for the solar panel to replenish the battery with sufficient power before charging multiple devices again, thus increasing the charging time of the devices.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1-9 One embodiment of this utility model is a wearable solar backpack, comprising:

[0035] The backpack body 1 has a flexible solar panel 4 fixedly installed on one side, and a battery pack for storing electrical energy is fixedly installed in the inner cavity of the backpack body 1. When the backpack body 1 is worn and used for outdoor sports, travel or daily commuting, the flexible solar panel 4 can convert light energy into electrical energy and transmit it to the battery pack for storage. The outer shell of the battery pack has power supply holes adapted to different types, and different types of electrical devices can be charged through the power supply holes (this is existing technology and will not be described in detail here).

[0036] Multiple back panels 2 are set on the outside of the backpack body 1, and flexible solar panels 2 are fixedly installed on one side of each of the multiple back panels 2. Two back panels 2 are detachably installed on one side of the backpack body 1, and flexible solar panels 2 are fixedly installed on one side of each of the two back panels 2.

[0037] Based on the applicant's understanding of the prior art, when wearing the backpack body 1 for outdoor sports, the weight of the backpack body 1, battery pack, electrical equipment, and two back panels 2 is relatively large, which will increase the burden on the wearer when hiking outdoors, thereby reducing the wearer's efficiency in outdoor hiking.

[0038] To solve the aforementioned technical problems, a U-shaped frame 3 is fixedly installed on one side of the backpack body 1. Multiple positioning blocks 5 are fixedly installed on one side of multiple back panels 2 along the vertical direction, and power plugs 7 for powering the battery pack are fixedly installed on the other side of multiple back panels 2. Multiple sliding grooves that are compatible with the positioning blocks 5 and power plugs 7 are fixedly installed on both sides of the inner cavity of the U-shaped frame 3. When wearing the backpack body 1 for outdoor sports, before the start of outdoor sports, the two back panels 2 are pulled out from the U-shaped frame 3 until the multiple positioning blocks 5 and power plugs 7 installed on both sides of the two back panels 2 are completely pulled out from the sliding grooves. This separates the two back panels 2 from the backpack body 1, thereby reducing the weight of the backpack body 1 and the burden on the wearer when hiking outdoors, and improving the efficiency of the wearer's outdoor hiking.

[0039] When the two back plates 2 are placed in the inner cavity of the U-shaped frame 3, the multiple positioning blocks 5 on both sides of the back plate 2 and the power plug 7 are all located in the inner cavity of the sliding groove, which can prevent the back plates 2 from swaying left and right or back and forth in the inner cavity of the U-shaped frame 3, so as to limit the position of the two back plates 2.

[0040] When the wearer carries multiple electrical devices or the devices have high power and require long-term power supply, two back panels 2 are needed. The two back panels 2 are unfolded in a straight line, and the flexible solar panel 4 and flexible circuit board 2 are simultaneously aligned with the sun. The flexible circuit board 2 and flexible circuit board 1 installed on one side of the two back panels 2 can simultaneously supply power to the battery pack, thereby improving the charging efficiency of the battery pack. This allows the battery pack to charge multiple electrical devices and high-power electrical devices at the same time, preventing the battery pack from running out of power and being unable to supply power to the devices.

[0041] One end of one of the back panels 2 is fixedly equipped with a power plug 28. The bottom of the inner cavity of the U-shaped frame 3 is provided with a power supply socket 20 that is compatible with the power plug 28. When the wearer is wearing the backpack body 1 and carrying the two back panels 2 during outdoor hiking, only the back panel 2 farthest from the backpack body 1 can be exposed to sunlight. At the same time, the power plug 28 at the bottom of the back panel 2 farthest from the backpack body 1 is inserted into the inner cavity of the power supply socket 20. At this time, the flexible solar panel 2 installed on the outside of the back panel 2 farthest from the backpack body 1 can continuously convert light energy into electrical energy and transmit it to the battery pack for storage, so as to charge the battery pack while the wearer is carrying the two back panels 2 for outdoor hiking.

[0042] Both sides of the U-shaped frame 3 are equipped with power outlets 9 that are compatible with the power plugs 7. When the user is camping outdoors or resting outdoors for an extended period of time, in order to ensure that the battery pack can continuously power multiple electrical devices and high-power devices, first place the backpack body 1 on a table or flat ground. Then, pull out the two back panels 2 from the inner cavity of the U-shaped frame 3, and place the two back panels 2 on both sides of the U-shaped frame 3, with the side of the back panel 2 with the flexible solar panel 2 facing the sky. Next, insert the two power plugs 7 installed on one side of each back panel 2 into the inner cavity of the power outlets 9 on both sides of the U-shaped frame 3. This will unfold the two flexible solar panels 2 and 4 in a "one" shape, and continuously power the battery pack through the two flexible solar panels 2 and 4, thereby improving the charging efficiency of the battery pack, so that the battery pack can continuously power multiple electrical devices and high-power devices, and reducing the charging time of the devices.

[0043] Based on the applicant's understanding of the prior art, when the two flexible solar panels 2 and 4 are unfolded in a "line" shape, there is a certain gap between the side of the back panel 2 away from the flexible solar panel 2 and the outer wall of the backpack body 1. If the power plug 7 is inserted into the inner cavity of the power socket 9, the power plug 7 will bear the entire weight of the back panel 2. Over time, this can easily lead to the deformation of the power plug 7, thereby affecting the power supply of the flexible solar panel 2 to the battery pack.

[0044] Two rows of connector blocks 11 are fixedly installed on one side of the backpack body 1. Multiple back panels 2, on the side away from the flexible solar panel 2, have multiple connector slots 6 that fit the connector blocks 11. Both the connector blocks 11 and the connector slots 6 are L-shaped. The number of connector blocks 11 and the distance between adjacent connector blocks 11 are the same as those between connector slots 6 (e.g., ...). Figure 9 As shown, when placing the two back panels 2 on both sides of the U-shaped frame 3, first align the multiple insertion slots 6 on one side of the back panel 2 with a row of insertion blocks 11, and continue to move the back panel 2 downwards until the ends of the multiple insertion blocks 11 away from the backpack body 1 are simultaneously in contact with the inner walls of the multiple insertion slots 6. Then push the back panel 2 to move it closer to the U-shaped frame 3 until the ends of the insertion blocks 11 away from the backpack body 1 are fully inserted into the inner cavity of the insertion slots 6. At this time, the two power plugs 7 installed on one side of the back panel 2 are fully inserted into the inner cavity of the power supply sockets 9 on both sides of the U-shaped frame 3, thus achieving the connection between the back panel 2 and the outer wall of the U-shaped frame 3. The cooperation between the insertion blocks 11 and the insertion slots 6 can support the bottom of the back panel 2, preventing the power plugs 7 from being forced to bear the full weight of the back panel 2 due to the suspension of the bottom of the back panel 2 and deforming, and preventing the deformation of the power plugs 7 from affecting the power supply of the flexible solar panel 2 to the battery pack.

[0045] The top of the U-shaped frame 3 has two symmetrical threaded holes. Limiting bolts 15 are installed in the inner cavities of both threaded holes via threaded engagement. A telescopic plate 14 is rotatably sleeved on the outer wall of the limiting bolt 15. A positioning post 13 is fixedly installed at one end of the telescopic plate 14. Positioning holes 12, matching the positioning posts 13, are opened on one side of the top of each of the multiple back plates 2. When two back plates 2 are placed inside the cavity of the U-shaped frame 3, and their bottoms are flush with the bottom of the cavity, the tops of the two back plates 2 are flush with the top of the U-shaped frame 3. Then, the small end of the limiting bolt 15 is inserted into the threaded hole. Inside the cavity of the perforated plate, rotate the telescopic plate 14 to make the central axis of the positioning post 13 coincide with the central axis of the positioning hole 12. Then, continue to rotate the large end of the limiting bolt 15 and ensure that the telescopic plate 14 is in a stable state until the bottom of the telescopic plate 14 is in contact with the top of the U-shaped frame 3. At this time, the positioning post 13 is fully inserted into the cavity of the positioning hole 12, preventing the back plate 2 from wobbling up and down in the cavity of the U-shaped frame 3. This fixes the back plate 2 placed in the cavity of the U-shaped frame 3 and prevents the back plate 2 from falling out of the cavity of the U-shaped frame 3 when the user is hiking or exercising outdoors.

[0046] When the two back plates 2 and the U-shaped frame 3 are arranged in a straight line, the positioning pin 13 can be inserted into the inner cavity of the positioning hole 12 again by adjusting the length and direction of the telescopic plate 14. This limits the back plate 2 located outside the U-shaped frame 3 and prevents the back plate 2 from detaching from the outer wall of the U-shaped frame 3.

[0047] The telescopic plate 14 consists of two sliding plates of different sizes. One end of the larger sliding plate has a groove, and the other end of the smaller sliding plate is slidably installed within the groove. One end of the positioning post 13 is fixedly connected to the end of the smaller sliding plate (e.g., ...). Figure 6 As shown, the distance between the positioning post 13 and the limiting bolt 15 can be changed so that the positioning post 13 can be smoothly inserted into the inner cavity of the positioning hole 12 to limit the back plate 2 at different positions.

[0048] The back panel 2, flexible solar panel 2, U-shaped frame 3, and positioning block 5 constitute the extension component. The extension component can increase the charging power of the battery pack and can be assembled with the backpack body 1, thus enabling the extension component to be carried around. At the same time, the two flexible solar panels 2 and 4 continuously supply power to the battery pack, which can increase the charging power of the battery pack, thereby effectively improving the charging efficiency of the battery pack. This allows the battery pack to continuously supply power to multiple electrical devices and high-power electrical devices, reducing the charging time of electrical devices.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
